Thelazia callipaeda is the main causative organism in thelaziasis, commonly infecting orbital cavities and associated tissues of carnivores. Thelazia callipaeda infection is rarely reported in humans, especially in infants.
A 5-month-old male infant presented with 2 weeks of redness and increased secretions in the left eye. On examination, the left eye revealed the presence of one creamy thread-like mobile worm in the conjunctival sac. During surgical exploration, a total of 11 worms were extracted from the left eye. The worms were morphologically identified as seven female and four male T. callipaeda. Ocular symptoms resolved rapidly after the removal of the worms, with no recurrence after the 6-month follow-up.
We present here detailed clinical and morphological information pertaining to T. callipaeda infection, which is considered to be a probably neglected parasitic disease of the eye. This case illustrates the importance of including thelaziasis into the differential diagnosis of ocular surface diseases, especially in infant patients.
Thelazia callipaeda 是嗜眼线虫病的主要病原体，常感染肉食动物的眼眶和相关组织。人眼感染嗜眼线虫的情况很少见，尤其是在婴儿中。
一名 5 月龄男婴因左眼发红伴分泌物增多 2 周就诊。检查发现左眼结膜囊内有一条乳白色线状活动虫体。手术探查时，从左眼共取出 11 条虫体。这些虫体经形态学鉴定为 7 条雌性和 4 条雄性 Calliphora vicina。虫体取出后，眼部症状迅速缓解，随访 6 个月无复发。
我们在此详细介绍了嗜眼线虫感染的临床和形态学信息，该病被认为是一种可能被忽视的眼部寄生虫病。本例说明了将嗜眼线虫病纳入眼表面疾病鉴别诊断的重要性，尤其是在婴儿患者中。
